MIXING-MACHINE.

Specification of Letters Patent.

Application filed April 11, 1910.

Patented Oct. 18, 1910.

Serial No. 554,736.

To all whom it may concern:

lie it known that I, Nioxoms 1. VLA- :uorxnns, citizen of the United States, residing at Fort \Vorth, in the county of Tar- ].ant and State of Texas, have invented certain new and useful Improvements in Mixing-hflachines, of which the following is a specification.

This invention relates to eonfectionersmachines and particularly a mixing machine.

The object of the invention is to provide a macl'iine having a common driving means, horizontal and vertical mixing connections and supports for the various parts.

A further object resides in (lumping and pouring means for one of the mixers and other particular maehanism.

Finally the object of the invention is to provide means of the character described that will be strong, durable, efficient, and easy of operation, simple and comparatively inexpensive to construct, and also in which the several parts will not be likely to get out of working order.

with the above and other objects in view, the invention has relation to certain novel features of construction and operation, an example of which is described in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the machine, Fig. 2 is a plan view, Fig. 3 is a detail in section of one of the vertical mixers, Fig. 1 is a vertical section of a portion of the machine, Fig. 5 is an end elevation with the mixing vat in section, and Fig. 6 is a horizontal cross sectional view taken on the line S-D of Fig. 4:.

In the drawings the numeral 1, designates a central stand or pedestal having a ring plate 2 secured on its top and resting on an extended base 3. On the ring plate a pair of opposed bearing boxes 4 are secured and receive a horizontal drive shaft 5. At right angles to the shaft 5 counter shafts 6 and 7 are mounted in bearing boxes 8 disposed on opposite sides of the ring plate but nnalined. It will be noted that the boxes 4: and 8 are shaped to conform to the ring plate. By this arrangement not only a saving in metal is had, but the open portion of the ring plate permits gears to be mounted on the shafts between the boxes.

The forward box 1 has a forwardly extending sleeve 9 terminating in a housing 10. The shaft 5 extends through the sleeve to the housing and has fixed on its ends therein a vertical bevel gear 11. A mixer shaft 12 extends vertically through the housing in which it may be moved vertically through bearings 13. A bevel gear ltmeshing with the gear 11 is fixed on the shaft 12. For raising the shaft and also for throwing the gears out of mesh, a grooved collar 15 is secured on the mixer shaft just below the gear 1 1', which collar receives the yoke end of a horizontal lever 16 pivoted at the side of the housing and operating through a slot therein. By depressing the outer end of the lever the gear 1 1 and shaft 12 are raised.

The shaft 12 depends from the housing and has a sleeve 17 on its lower end held by a set screw 18. 011 opposite sides of the sleeve mixing blades are fastened. These blades each have a broad rounded paddle 19 and a slotted stem 20 by which they may be adjusted radially and axially. A mixing vessel 21 is supported on a shelf 22. The mixing blades are rotated in this vessel by the shaft 12 and are raised therewith by the lever 16. When it is desired to remove the vessel the shelf 22 may be lowered by turning a hand wheel 10 which rests on a supporting sleeve 11 and engages with threads of a screw 42 on the shelf.

The shaft 6 before referred to has a bevel gear 23 on its inner end which meshes with a like gear 24 fixed on the shaft 5. On the outer end of the shaft 6, a spur gear 25 is fastened and meshes with a pinion 26 thereunder. This pinion is fixed on the inner trunnion 27 of a horizontal beater 28 having its trunnion 27 mounted to-revolve in the upper ends of standards 29. The standards are secured on a platform 30 extend ing from the stand 1 and supported at its outer end by legs 31. Between the standards a mixing vat 32 is horizontally hung on the beater trunnions 27 and is free to be swung at any time. This vat has particularly high sides which prevent splashing and a rounded bottom in cross section. For swinging the vat and dumping its contents, a transverse gear segment 33 is provided on the bottom of the vat and meshes with a pinion 34: fixed on a shaft 35 supported by the standards 29. The shaft 35 has a handle 36 on its outer end by which it may be turned and the vat swung or dumped. To

cause the material to pour from the vat, a mouth and lip construction 37 is provided at one side and upper edge.

The bearing box 8 through which the shaft 7 extends connects with a sleeve 38 Which terminates in a housing 39. WVithin the housin a miter gear 45 is keyed on the shaft 7 am? meshes with a pinion 46 mounted on a vertical shaft 47 extending through the housing. A pinion 48 fixed on a sleeve 49 through which the shaft 47 passes meshes With the underside of the miter gear 45 so that it may be revolved in the opposite direction to that in which the shaft 47 i revolved.

The lower end of shaft 47 carries a collar 50 which is arranged to engage over the squared end of a spindle 51 pivoted in the bottom of a receptacle 52 while the lower end of the sleeve 49 carries a similar collar Which engages with a square sleeve 53 on a lid 54 which covers the receptacle 52 and is fixed to cause the receptacle to revolve on a pivot 55 Which turns in a bearing 56 secured in the bottom of a receptacle 57. The spindle 51 carries mixing blades 58 arranged in staggered relation and scraper 59 Which keeps the sides of the receptacle clean.

he miter gear 45 may he slipped back on the shaft 7 so as not to mesh with the pinions 46 and 48 and the receptacle and spindle will be brought to rest. After the gear 45 has been slipped back the shaft 47 and sleeve 49 may be raised enough to dis connect with the receptacle and the spindle by pressing down on a lever 60 which engages with a loose collar 61 on the shaft 47. A pulley 62 mounted on the shaft 5 transmits power to the entire machine.

In mixing certain confections it is necessary to first mix several of the ingredients thoroughly giving them a slow but positive rotary movement. This may be accomplished by the paddles 19 in the vessel 21 but as other ingredients are added the matter would form into a body too heavy to be worked by paddles; it is then transferred into mixing vat 32 where the mixing is carried on by beater 28. The material may then be transferred to the receptacle 52 and revolved therein until it is cool enough to dip or to be otherwise used.

It is to be observed that the receptacle 57 is supported on a platform 69 extending from the central stand. Motion is imparted to the shaft 7 by a miter gear 68 attached thereto and meshing with a similar gear fixed on the shaft 5. For sliding the gear 45 out of mesh with the pinions 46 and 48-, the gear is provided with a grooved hub 65 engaged by the yoke end of a lever 66 pivoted in the side of the housing 39 and outward therefrom.
